New Mexico Car Tax and Fees at a Glance

How the New Mexico Excise Tax Is Calculated

Excise tax = (price paid − trade-in) × 4%

New Mexico’s motor vehicle excise tax (MVET) takes the place of gross receipts tax on vehicle sales. It’s the same 4% everywhere, with no city or county add-on. A dealer usually collects it with your title paperwork. Otherwise you pay it to the MVD when you title the car.

New Mexico is one of a few states with a flat excise instead of sales tax. South Dakota also uses a flat 4% excise tax.

Does a trade-in lower the tax?

Yes. The tax is 4% of the price paid less any trade-in credit. A $35,000 car with a $10,000 trade-in is taxed on $25,000.

How are private sales taxed?

On the price you paid, with one catch. If that price is less than 80% of the car’s NADA average trade-in or wholesale value, the MVD uses the NADA value instead. That stops people from writing a low price on the bill of sale.

Other states handle this differently. Texas taxes private sales on presumptive value, using 80% of a standard value.

How Much Is Car Tax in New Mexico?

Example 1: New car from an Albuquerque dealer

Assumptions: $35,000 price, $10,000 trade-in, car over 3,000 lbs, one-year registration.

Add the small MVD title and transaction fees. From 2027, add $70 if it’s an EV.

Example 2: Private sale below 80% of NADA value

You pay $6,000 for a car with a $9,000 NADA value. Since $6,000 is under 80% of $9,000 ($7,200), the tax uses $9,000: $360.

Example 3: Titling late

If the tax in Example 1 is $1,000 and you wait more than 90 days to title, the 50% penalty adds $500, for $1,500 in total.

New Mexico Registration Fees

Senate Bill 2 raised passenger registration fees starting July 1, 2026. You can register for one or two years. A two-year registration costs twice the yearly fee.

Add the $1.50 tire recycling fee. Before July 1, 2026, the same bands were $27, $39 and $56 for newer cars.

New Mexico EV and Plug-In Hybrid Fees

New Mexico doesn’t charge an EV fee in 2026. Starting January 1, 2027, electric and plug-in hybrid vehicles up to 26,000 lbs pay a yearly fee on top of registration:

Gifts, Late Titles and Out-of-State Purchases

Gifts

A gift isn’t a sale, so no excise tax is due. Both the giver and the person receiving the car sign a notarized Affidavit of Gift of Motor Vehicle (MVD-10018).

Title within 90 days

New Mexico residents must title a car within 90 days of buying it in the state or bringing it in from another state. After that, a 50% penalty is added to the excise tax.

Buying out of state

If you paid sales, excise or a similar tax to another state, that amount can be credited against the New Mexico excise tax. Bring proof. Shopping next door in Colorado means paying Colorado’s state and local sales tax, which you can then use as a credit here.

Common Mistakes to Avoid

• Adding gross receipts tax. Cars pay the 4% excise instead.
• Writing a low private-sale price. The MVD uses NADA value if it’s under 80%.

• Skipping the gift affidavit. Without it, the MVD treats the transfer as a sale.
